hearing horn (digital)

Post by bwozniak »

I am working on a school project with my kids and we are trying to create a (digital) hearing horn. We purchased Adafruit Mono 2.5W Class D Audio Amplifier - PAM8302, and Adafruit I2S 3W Class D Amplifier Breakout - MAX98357A along with Electret Microphone Amplifier - MAX4466 with Adjustable Gain, and Mini Oval Speaker - 8 Ohm 1 Watt, and 3.7v lithium ion battery. We cant figure out how to get it to work. Any help would be great!!!!

Were you following a particular guide of ours that you selected this assortment of hardware?

We are trying to make it as small as possible. Some of your components we selected are perfect sizes. We are getting feed back and not clear sound when trying.

Can you post pictures of the project with the wiring and location of the boards?
